All,
In early descriptions of QPI, this capability (a remote QPI agent's [on say an FPGA or GPU
accelerator] ability to stimulate a QPI processor to prefetch data to its cache, avoiding memory),
was listed as a possible feature of QPI. This has obvious potential benefits in globalizing
distributed memory and reducing remote memory reference data copies. I am guessing that
such a feature would be important in SGI's Tukwila based UltraViolet system, but am wondering
if it is part of what will be supported on the soon-to-be-released Nehalem EPs? A side
questions would be "Does HyperTransport allow for something similar?"
Thanks,
rbw
